QMB 3200 FINAL
STACEY BROOK
1. In general, higher confidence levels provide larger confidence
intervals. One way to have high confidence and a small margin
of error is to: - CORRECT REPLY>>> -increase the
sample size.
2. In stratified random sampling: - CORRECT REPLY>>>
-randomly selected elements within each of the strata form the
sample.
3. The test statistic for the Fisher's LSD test follows the: -
CORRECT REPLY>>> -t distribution.
4. The effect produced when the levels of one factor interact with
the levels of another factor in influencing the response variable
is called: - CORRECT REPLY>>> -interaction.
, 5. The p-value: - CORRECT REPLY>>> -must be a
number between 0 and 1.
6. The logic behind ANOVA is based on the development of two
independent estimates of: - CORRECT REPLY>>> -
the common population variance.
7. As the sample size increases, the margin of error: -
CORRECT REPLY>>> -decreases.
8. If two large independent random samples are taken from two
populations, the sampling distribution of the difference
between the two sample means: - CORRECT
REPLY>>> -can be approximated by a normal distribution.
9. Which of the following is(are) true?
I. The mean of a population depends on the particular
sample chosen.II. The standard deviations of two
different samples from the same population may be
the same.III. Statistical inferences can be used to draw
conclusions about the populations based on sample
data. - CORRECT REPLY>>> -II and III
